Middle-click

Many mice and some touchpads have a middle mouse button. On a mouse
with a scroll wheel, you can usually press directly down on the scroll
wheel to middle-click. If you don’t have a middle mouse button, you
can press the left and right mouse buttons at the same time to
middle-click.

On touchpads that support multi-finger taps, you can tap with three
fingers at once to middle-click. You have to
enable tap clicking in the
touchpad settings for this to work.

Many applications use middle-click for advanced click shortcuts.

In the Activities overview, you can quickly open a new
window for an application with middle-click. Simply middle-click on the
application’s icon, either in the dash on the left, or in the applications
overview. The applications overview is displayed using the grid button in the
dash.

Most web browsers allow you to open links in tabs quickly with the
middle mouse button. Just click any link with your middle mouse button, and
it will open in a new tab.

In the file manager, middle-click serves two roles. If you
middle-click a folder, it will open in a new tab. This mimics the
behavior of popular web browsers. If you middle-click a file, it
will open the file, just as if you had double-clicked.

Some specialized applications allow you to use the middle mouse
button for other functions. Search your application’s help for
middle-click or middle mouse button.
